IMPROVEMENT IN STOVE-GRATES. A

Specification forming part of Letters Patent No. 171,483, dated December28, 1875; application filed 7 December 6, 1875.

Figure 1 is a top view of a fire-grate containing my improvements. 1

There are six bars shown and seven spaces. The six bars are made andhung in pairs or sections, each section upon ordinary journals in theframe inclosing them. The faces of the bars are checked with alternatingelevations and depressions.

Fig. 2 is an end elevation. Fig. 3 is a transverse vertical sectiontaken in the line a; as of Fig. 1. It shows the grate-bars in theirnormal condition, as seen in Fig.1. Fig. 4 is a transverse verticalsection taken in the same line as Fig. 3, and showingthe three sectionsof the fire-bed turned down, in which position the refuse products ofcombustion may be discharged very rapidly. Fig. 5 is a front view of thehanger D, and shows how the bar 0 is held up by its short arm.

A is the frame; a a a, journal-bearings; B, grate-bars in sections; 1),the supporting-arm from D; O, the manual bar for operating the grate; cc c, stems from the operating-bar; D,

hangers from the frame A; d, a spring, used.

in this case as a substitute for more weight required in thebar O tokeep it more firmly in place; E, bifurcated pendants from-the gratebars;F, a shoulder upon the operating-bar G, placed at such a point from itsstop b as to allow considerable movement, by which the fire-bed can bethoroughly agitated without any danger of dumping it. If, however, it isdesired to discharge the refuse product of combustion faster than it canbe done with this limited motion, by lifting the manual end of theoperating-bar a little it will pass over the stop, and the largestpossible freedom of motion will then be obtained.

It is thus seen that I do not depend upon the shoulder F to keep thegrate level, though another shoulder or stop similar to this might beused for that purpose, if desired.

Whenever the bar (1 is of suflicient-Weight it will hold the grate atany point desired at rest. The stop is'to guide the operator inagitating the grate, so that he will notopen the spaces enough to dumpthe grate uninten tionally.

I claim as my invention- 1. The frame A, provided with journal-bearingsfor grate-bars, and with hangers D, in

combination with an operating lever or bar, 0, substantially as shown. i

2. The grate-bars B, pivoted at a, and provided with pendants E, incombination with an operating-bar, O, substantially as shown.

3. The operating-bar 0, provided with stems c, in combination withgrate-bars B, substantially as shown.

4.. The shoulder F, placed upon the operating-bar O, and adjusted to.check its motion, substantially as and for the purpose herein set forth.

5. In combination, the frame A, bars B, pivoted as shown, operating-bar0, arranged to operate substantially as shown.
